According to Dale S. Beach, Human resource planning is a process of determining and assuring that the organisation will have an adequate number of qualified persons, available at the proper times, performing jobs which meet the needs of the enterprise and which provide satisfaction for the individuals involved.
How much sleep do teens need? Based on current data, we think that most teens need on the order of 9-plus hours nightly to have optimal sleep. The NSF poll data indicate that most teens fall short of this goal, many by a considerable amount. Although we think that the need for sleep does not really change across adolescence, the amount of sleep young people get does decrease in older teens.
On average, teens need about 8 1/2 to 9 1/2 hours of sleep each night. If you fall asleep at 10 p.m., you'd need to sleep until 7 a.m. to meet this requirement. That's not always possible, especially if you have to be up before dawn to catch the bus or make swim team practice. Many teens suffer with chronic insomnia.
